Airtac MAC Stainless Steel Mini Air Cylinder MAC20X105SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X105SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 105mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X105SCA
Pivot points built in: the CA back cover of the MAC20X105SCA takes a clevis pin directly, so swing links and lever arms connect without extra brackets. This double-acting 20 mm bore pushes 157 N and pulls 132 N at 0.5 MPa across a 105 mm stroke. Work to about 8 kg of vertical lift rather than the raw 16 kgf thrust and the mechanism will not strain near stall.
Because the piston magnet is factory standard, a DMSG or CMSG switch reports extension and retraction the day it arrives. The stainless round barrel with its hard-chrome rod also tolerates washdown splash that would rust a painted mini within months. Speed spans 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X105SCA Is Used
Sorter flip arm
Flips small parcels between conveyor lanes on a sortation line, the CA pivot driving the arm through its 105 mm arc.
Aisle-entry gate
Swings a safety gate open where reach trucks enter an aisle, 157 N of push working against a light spring latch.
Bin-tip assist
Tilts small parts bins at a press-feed station, cushioned ends settling the bin gently at both limit positions.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X105SCA the Right Cylinder?
Oversize or undersize deliberately: 100 N from the 16 mm bore or 245 N from the 25 mm bore brackets this 157 N class. With the extra 5 mm over a 100 mm model, check rod straightness - side load on a 105 mm stroke can bend the 8 mm rod if the tooling is not guided. When air is lost the rod simply drifts, so specify a pilot check valve if the swing arm must park under load.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC20X105SCA FAQ
Push 157 N and pull 132 N at 0.5 MPa; push 220 N at 0.7 MPa; theoretical maximum 32 kgf at 1.0 MPa. Pressure runs 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, stroke 105 mm, rod thread M8x1.25, port 1/8 inch.
It provides a pivot boss that accepts a pin for swing-arm or clevis linkage. Combine it with an SDB pivot bracket or LB foot when the body itself also needs support, keeping the 8 mm rod free of side load.
